Quick overview
Quick overview This workflow runs on a schedule (or manually) to read Cloudflare firewall events via the Cloudflare GraphQL API, aggregate activity by client IP, and compute deterministic bot-risk scores with evidence-based signals, then routes results into block recommendations, a review queue, or low-risk monitoring. How it works Runs every 15 minutes (or on manual start) and loads the scoring configuration, including zone selection, look-back window, and thresholds. Calls the Cloudflare REST API to discover available zones and resolves the final list of zones to assess. Builds a Cloudflare GraphQL query for each zone and fetches recent firewallEventsAdaptive events within the configured time window. Aggregates the returned events by zone and client IP, calculating indicators like probe-path hits, 404 rates, distinct paths, and challenge outcomes. Scores each IP using a deterministic ruleset (no AI) and assigns a recommendation band (monitor, recommend_review, or recommend_block) with explainable signals. Formats high-risk offenders into copy/paste block or managed-challenge recommendations (including a suggested Cloudflare IP List payload) and formats medium-risk offenders into a review message, while low-risk results are simply logged. Setup Create a Cloudflare API token with Zone → Zone : Read and Zone → Analytics : Read, then add it to an n8n HTTP Header Auth credential as Authorization: Bearer . Update the Configuration code to set zoneTags (or leave empty for auto-discovery), windowHours, eventLimitPerZone, and the review/block thresholds. Replace the two “SET UP:” placeholder steps with your preferred outputs (for example Slack, email, Google Sheets, or a SIEM destination) and map the formatted recommendation/review text into those nodes.
